The maniac who shot 13 people dead in a Binghamton immigration center before killing himself was described Friday as an angry loner who loved guns, hated America and talked about assassinating the President.

Greene said Voong's conversations often focused on weapons. "He went to target practice on Saturday. He said he had two guns, one in his glove compartment. He was always talking about his guns."

But around his home in nearby Johnson City, Voong was known as an attentive son and quiet neighbor.

Neighbors said he was often seen helping his dad, Henry, tend the succulent apples and berries he grew behind his modest frame house.

"They're a nice family, they're great neighbors," said Barbara Monell, 25, who lives next door. "My nephews go over to eat his apples and berries. They're always invited to come over and eat his fruit."
